Detailed Description

An OO event demultiplexor and event handler dispatcher for Win32 <MsgWaitForMultipleObjects>.

The ACE_Msg_WFMO_Reactor is an OO event demultiplexor and event handler Reactor. It differs from <ACE_WFMO_Reactor> by its ability to react on Windows messages. It is needed when the task should serve also as a COM/DCOM server.


Constructor & Destructor Documentation

ACE_Msg_WFMO_Reactor::ACE_Msg_WFMO_Reactor ACE_Sig_Handler = 0,
ACE_Timer_Queue = 0
 

Initialize <ACE_Msg_WFMO_Reactor> with the default size.

ACE_Msg_WFMO_Reactor::ACE_Msg_WFMO_Reactor size_t  size,
int  unused = 0,
ACE_Sig_Handler = 0,
ACE_Timer_Queue = 0
 

Initialize <ACE_Msg_WFMO_Reactor> with size <size>. Two slots will be added to the <size> parameter which will store handles used for internal management purposes.

ACE_Msg_WFMO_Reactor::~ACE_Msg_WFMO_Reactor void   )  [virtual]
 

Close down the ACE_Msg_WFMO_Reactor and release all of its resources.


Member Function Documentation

virtual int ACE_Msg_WFMO_Reactor::alertable_handle_events ACE_Time_Value max_wait_time  )  [virtual]
 

Reimplemented from ACE_WFMO_Reactor.

virtual int ACE_Msg_WFMO_Reactor::alertable_handle_events ACE_Time_Value max_wait_time = 0  )  [virtual]
 

Reimplemented from ACE_WFMO_Reactor.

int ACE_Msg_WFMO_Reactor::dispatch_window_messages void   )  [protected, virtual]
 

Dispatches window messages.

Reimplemented from ACE_WFMO_Reactor.

virtual int ACE_Msg_WFMO_Reactor::handle_events ACE_Time_Value max_wait_time  )  [virtual]
 

This method is just like the one above, except the <max_wait_time> value is a reference and can therefore never be NULL.

Reimplemented from ACE_WFMO_Reactor.

virtual int ACE_Msg_WFMO_Reactor::handle_events ACE_Time_Value max_wait_time = 0  )  [virtual]
 

This event loop driver blocks for up to <max_wait_time> before returning. It will return earlier if timer events, I/O events, window events, or signal events occur. Note that <max_wait_time> can be 0, in which case this method blocks indefinitely until events occur.

<max_wait_time> is decremented to reflect how much time this call took. For instance, if a time value of 3 seconds is passed to handle_events and an event occurs after 2 seconds, <max_wait_time> will equal 1 second. This can be used if an application wishes to handle events for some fixed amount of time.

<MsgWaitForMultipleObjects> is used as the demultiplexing call

Returns the total number of <ACE_Event_Handler>s that were dispatched, 0 if the <max_wait_time> elapsed without dispatching any handlers, or -1 if an error occurs.

The only difference between <alertable_handle_events> and <handle_events> is that in the alertable case, MWMO_ALERTABLE is passed to <MsgWaitForMultipleObjects> for the <bAlertable> option.

Reimplemented from ACE_WFMO_Reactor.

DWORD ACE_Msg_WFMO_Reactor::poll_remaining_handles DWORD  index  )  [protected, virtual]
 

Check for activity on remaining handles.

Reimplemented from ACE_WFMO_Reactor.

DWORD ACE_Msg_WFMO_Reactor::wait_for_multiple_events int  timeout,
int  alertable
[protected, virtual]
 

Wait for timer and I/O events to occur.

Reimplemented from ACE_WFMO_Reactor.
